Abstract: CIRCUIT FOR MAINTAINING THE DC VOLTAGE ON AN ELECTRICALLY ISOLATED TELECOMMUNICATION LINE AT A REFERENCE LEVEL     Abstract A DC reference voltage circuit in a line interface circuit for maintaining the DC voltage on an electrically isolated communications line at a reference level such as ground for private branch exchanges using ground start supervisory signaling.  The DC reference voltage circuit comprises a low-pass filter, a difference amplifier and two voltage-to-current sources each having a high output impedance.  The low-pass filter passes only the voltage on the line below a predetermined frequency.  The difference amplifier subtracts the passed voltage from a ground reference level to form a difference voltage.          Depending on the polarity of the difference voltage, the two voltage-to-current sources provide source and sink currents to and from the line to maintain the DC voltage on the line at the reference level.  A load resistor also included in the feedback circuit keeps the circuit from oscillating where the phase shift of any signal through the circuit is an integer multiple of 360 degrees. The high output impedance of the two voltage-to-current sources does not effect the impedance balance on the line.

Abstract: ABSTRACT: "Circuit arrangement for converting an alternating current signal into a binary signal".       The described circuit arrangement converts an al-ternating current signal into a binary signal when the level of the alternating current signal exceeds an initial threshold voltage. During the period of time in which the alternating current signal is delivered, the threshold voltage is reduced. If the level of the alternating current signal falls short of the reduced threshold voltage, then the delivery of the alternating current signal is in-terrupted and the threshold voltage is again increased to its initial value. This hysteresis during switch-on and switch-off of the binary signal results in either an error-free binary signal being supplied or no binary signal at all.

Abstract: ABSTRACT DISTRIBUTED CACHE IN DYNAMIC RAMS A microcomputer memory system is organized into a plurlaity of banks (16).  Each bank consists of an array of static column mode dynamic random access memories (DRAMs)  of 5 the type having an on-chip static buffer for storing an entire row.  The static buffers associated with each bank functions as a distributed cache (24) to hold the last accessed row for the associated bank.  A memory controller (18) receives real addresses from a CPU (15) or other device on the memory bus (14) and extracts bank and row numbers from the address.  The memory controller determines whether the accessed row for a memory bank is in the distributed cache and, if it is, accesses the distributed cache for that bank.  Otherwise, the memory controller switches the 5 contents of the distributed cache with the contents of the addressed row for that bank.

Abstract: INTEGRATED CIRCUIT CHIP PACKAGE          Abstract of the Disclosure An integrated circuit is mounted on, and electrically connected to an underlying substrate by the flip-chip technique.  In this technique, the chip is inverted and bonding pads on the chip are soldered to correspondingly located bonding pads on the substrate.  By the invention a continuous ribbon or loop of solder or polymer extends between the chip and substrate surfaces and defines a sealed cavity.          Because the interior of the cavity is sealed from contaminants, conducting leads of the chip or substrate can be left uncovered within the cavity so reducing the capacitance of high frequency circuits.          The substrate can be a connection medium such as a printed circuit board or could be another integrated circuit chip.                                 -i-

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a valve gated single cavity injection molding system wherein the valve pin actuating mechanism is cooled by circulating hydraulic fluid through it.  The cylinder is mounted in a cylinder housing inside a dome portion of a heated manifold housing.  The cylinder housing has a wing portion extending out openings in each side of the manifold housing.  Each wing portion has an inlet duct and an outlet duct for hydraulic fluid across which a pressure differential is applied.  The ducts connect to circumferential channels which extend around the outside of the cylinder and lead to respective openings into the cylinder.  Thus, the application of hydraulic fluid pressure during operation circulates hydraulic fluid through the actuating mechanism.  The cooling which results extends the operating life of the mechanism, particularly the seals and O-rings.

Abstract: AUTOMATIC HEIGHT CONTROL FOR A LATERALLY PIVOTED HARVESTER HEADER         Abstract of the Disclosure In a combine harvester, an array of ground engaging skid shoes or feelers spans the header platform and is divided into right- and left-hand groups, each group associated with a position sensor switch.  Each switch transmits to an electrohydraulic control system, a signal representative of the relative position of the skid shoe closest to the ground in its half of the platform.  The combined left- and/or right-hand signals are transduced to control platform vertical adjustment and lateral tilt automatically.  In one embodiment, a pair of lift cylinders, acting in unison, control platform elevation while a third cylinder is dedicated to tilt control.  In other embodiments, paired lift cylinders are controllable independently, to provide both height and tilt control.  Supporting the feeder conveyor lower shaft and the header main drive shaft in the laterally pivotable lower forward portion of the feederhouse permits direct transfer of crop material from the platform auger to the feederhouse conveyor and also simplifies header drive arrangements.

Abstract: COMPENSATION FOR FINE LINE PRINTS                       ABSTRACT            In an electrophotographic printer or the like, compensation is provided for environmental effects (temperature, humidity, photoconductor aging, etc.) which would otherwise affect print quality.  Analy-zing print data allows identification of compensation locations; those are locations at which compensation is most critical, such as single pel lines.  A series of clock pulses of varying phase displacement are employed, and selected based on environmental variations, so as to modify the print data at the identified compensation locations.  The print data comprises a series of pulses.  Compensation to control the width of lines perpendicular to the scan direction is effected by selectively advancing the leading edge of pulses defining a white/black transition and delaying the trailing edge of pulses defining the black/white transition.  This control then affects the duration of the print pulses.  For lines which are parallel to the scan direction width control is effected by adding gray pulses, both the leading and trailing edges of these gray pulses are controlled in accordance with environmental vari-ations.  Accordingly, the duration of the gray pulse is also controlled.
